Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair dye composition, and more particularly to a hair dye composition that can easily dye gray hair gradually black during daily hair care activities.

[Prior art]

Conventionally, hair dyes include (1) Eve's, a two-component type based on para-phenyl diamine, which is left on for a certain period of time after application, and then washed off to dye the hair;
2) - Temporary hair dyes that temporarily attach black substances to gray hair are known.

Type (1) has a good color tone and does not fade with shampoo, and is currently the most widely used type, but it has the major drawbacks of being time-consuming and allergic. In addition, type (2) is easy to use and rarely shows any allergenic properties, but it has the disadvantage that it easily comes off with shampoo.
None of these types necessarily satisfied the needs of users.

[Problem to be solved by the invention]

The present invention was made in view of the above circumstances, and it is an object of the present invention to provide a hair dye composition that can easily dye gray hair gradually black during daily hair care activities.

As a result of intensive research to achieve the above object, the present inventors found that the first agent contains a ferrous salt and at least one compound selected from propyl gallate, ascorbic acids, and plant extracts. The present inventors have discovered that the above object can be achieved by incorporating a nonionic surfactant into at least one of the first agent and the second agent, and have completed the present invention.

That is, the hair dye composition of the present invention consists of a first agent containing a ferrous salt and a second agent containing at least one compound selected from propyl gallate, ascorbic acids, and plant extracts; It is characterized in that at least one of the agent or the second agent contains a nonionic surfactant.

The ferrous salts that are essential components of the first agent of the present invention include ferrous chloride, ferrous sulfate, ferrous acetate, ferrous phosphate, and ferrous diate. Particularly preferred are ferrous chloride and ferrous sulfate.

The amount of ferrous salt to be blended is preferably 0.1 to 3% by weight based on the total amount of the hair dye composition of the present invention, particularly preferably O, S or 2% by weight. If it exceeds 3% by weight, the stability tends to deteriorate.

Further, the pH of the first agent is preferably 3 to 6, particularly preferably 4 to 5. If the pH is at the 3-end, the hair dyeing effect tends to be poor, and if the pH exceeds 6, the hair dyeing effect and stability tend to be poor.

The essential component of the second agent of the present invention is at least one compound selected from propyl gallate, ascorbic acids, and plant extracts.

The amount of propyl gallate to be blended is preferably 0.05 to 0.5% by weight based on the total amount of the hair dye composition of the present invention. Hair dyeing properties tend to be poor at the 0.05% by weight end.
Moreover, if it exceeds 0.5% by weight, stability tends to deteriorate.

As an ascorbic acid, L-ascorbic acid is used.

Includes L-dehydroascorbic acid or salts thereof. Examples of salts include metal salts of ascorbic acid such as magnesium ascorbyl phosphate and magnesium ascorbate sulfate; metal salts of ascorbic acid such as sodium L-ascorbate, potassium L-ascorbate, and calcium L-ascorbate; salt, sodium L-dehydroascorbate, potassium L-dehydroascorbate.

Examples include metal salts of dehydroascorbic acid such as calcium dehydroascorbate. Particularly preferred is L-ascorbic acid or sodium monoascorbate. The blending amount of ascorbic acids is preferably 0.5 to 5% by weight based on the total amount of the hair dye composition of the present invention. If it exceeds , stability tends to deteriorate.

Plant extracts include Acacia japonica, Ju, Gennoshoyu, Hamamelis, Horse chestnut, and Amacha.

Hypericum, St. Icusa, Rosemary Althea, Cinchona, Hawthorn, Kingin Chikara, Coltsfoot, Horsetail, Hops, Pine, Horsetail, Chamomile, Nettle,
Examples include peony, juniper, peach, and mixed plant extracts. Particularly preferred are Aspergillus japonica, Aspergillus japonica or Hamamelis. The blending amount of the plant extract is 0.00% in terms of evaporation residue based on the total amount of the hair dye composition of the present invention.
Preferably from 0.05 to 2% by weight, O,OS
If the weight percentage is at the end, the hair dyeing properties tend to be poor, and if it exceeds 2 weight percent, the stability tends to be poor.

In addition, examples of the nonionic surfactant to be blended in at least one of the first agent and the second agent include polyoxyethylene (hereinafter abbreviated as POE) oleyl ether, POE
POE alkyl ethers such as stearyl ether, PO
POE alkylphenyl ethers such as E nonylphenyl ether and POE octylphenyl ether, POE (
